MSPM0G3519-Q1: when using CPU reset, init clk will enter infinite loop

Part Number: MSPM0G3519-Q1
Other Parts Discussed in Thread: SYSCONFIG

We are debugging a new prototype.  

We encountered a problem during the debugging process.  when using CPU reset, the initialization clock will enter an infinite loop.   Only by using hardware reset can it return to normal

What ideas do you have to use CPU reset so we won't go into infinite loop?   see code below.

 

  • Hi Jonathan, this could be happening due to monitoring a clk that is either:

    A) not enabled in your sysconfig

    B) the source for the clk you are monitoring is not set to external HFXT or the frequency defined in your sysconfig doesn't match the XTAL frequency.

    Can you verify the two above items are set properly and see if that solves the issue?
